> Key: FLINK-19338
> URL: https://issues.apache.org/jira/browse/FLINK-19338
> Project: Flink
> Issue Type: Bug
> Components: Connectors / Common
> Affects Versions: 1.12.0, 1.11.2
> Reporter: Arvid Heise
> Assignee: Arvid Heise
> Priority: Major
>
> When a source subtask fails before the respective reader is registered in {{SourceCoordinatorContext}}, unregistering fails as it explicitly verifies that the reader has been registered before.
> The solution is to drop the assumption that all readers are registered when cleaning up subtasks.
